Week 22: Gears and Shafts

Shafts:

Shafts are long rods of metal that serve as an axle or a rotating part of a mechanisms. They usually have parts fixed onto them and transmit their rotational motion to them.

Gears:

Gears are parts designed to work on a shaft. Gears mesh with one another using their teeth and cause each other to rotate. By having gears of different sizes/teeth mesh, we can create gear ratios that increase or decrease speed or torque.

Bearings:

Bearings prevent shafts from shifting while still allowing them to rotate. They come in different shapes for different uses and allow for ease of spinning.

Set Collars:

Set collars clamp onto shafts, and are used to hold objects in place on shafts. They use set screws to adjust their positions, which are adjusted with allen keys.
